Poor performance of Ruby 1.8.7 when installed with MacPorts

arcadio

Hi,

I've just upgraded to Ruby 1.8.7 using MacPorts (ruby @1.8.7-
p72_1+thread_hooks) and while it runs flawlessly, the performance is
really really poor.

I'm talking in comparison with the Ruby distro that ships with
Leopard, and with my previous installation of 1.8.6 also done with
MacPorts.

For instance a bunch of rspecs i have take 6x to get executed, and ri
takes noticeably more time than previously to load any doc.

Is anyone experiencing the same problem? Do you know how to fix it?

Thanks in advance.

Fine, thanks for the info.

Do you know what is the exact issue with MacPorts though?

The same problem reported at ruby-list-45593.(but Japanese only)

Summary is below.
1. On MacOS X(10.5.5), Ruby1.8.7(p72) compiled with --enable-pthread excute slowly,
as Ruby use time of 70% at rb_call()->getcontext() in fib.rb

2. In MacPorts, ./configure with --enable-pthread option makes config.h using getcontext
like below
#define HAVE_GETCONTEXT 1
#define HAVE_SETCONTEXT 1

3. If you comment out these two lines, you will get normal speed Ruby1.8.7.

4. As Ruby1.9 don't use getcontext()/setcontext(), Ruby1.9 don't care --enable-pthread.

Wow, that was fast. Is the Ruby community great, or what? :) Thanks
for reporting back with the info.

Could someone explain this to to me. I checked the macports page a few
days back and it said it disables/deletes -enable-pthreads due to some
bug. So does that not mean that it's not there. As pointed above, it
uses thread_hooks instead.

1. Is there any commandline option or other way of my ascertaining
whether my install uses pthreads or not.

Another newb question:

2. One of the prev posts suggests altering config.h and running
/configure. However, if one is using sudo port install how does one do
this? I do not have a "configure" in my ruby folder and my config.h
(/opt/local/var/macports/software/ruby/1.8.7-p22_3+darwin_9_powerpc+thread_hooks/opt/local/lib/ruby/1.8/powerpc-darwin9.4.0/config.h)
does not contain GETCONTEXT.

Thanks.

apparently somebody said that the most recent macport of it now compiles
with pthreads disabled.

Maybe try with "ldd" on the ruby binaries--can't remember what the mac
equivalent is but it exists.

If you install it from source you should be able to get at it
right...not sure using macports.

Using MacPorts, you just have to perform the various steps of the
'install' task manually, like this:

% sudo port fetch ruby
% sudo port extract ruby
% sudo port configure ruby

Now go in the work directory and change what you need. You can see
where that directory is by typing:
% port file ruby

After that, you can continue normally:
% sudo port install ruby

Thanks a lot.

btw, will installing 1.9 from macports create a separate executable such
as ruby1.9 so we can run 8 and 9 in parallel. Or overwrite?


Is there any way via macports to have both running in parallel.
Thanks.
